i haven't opened this particular package yet, but Energizer batteries have always worked for me in the past, so i see no reason to assume otherwise. for whatever it's worth, i use either Energizer or Duracell batteries for everything, and stay away from mongrel brands.

Great Batteries! Energizer is the only batteries I use, Last the longest! I use flameless candles around the house and energizer lasts the longest.

We keep a supply of this brand of 9-volts on hand for every hurricane season. They are long lasting in service and they last for years in storage if kept in their original packaging. Cheaper than the copper colored brand.

Great price on these 9 volt batteries! It’s that time of the year to replace all batteries in the smoke detectors.

Package was damaged in shipment but the product was not.

Energizer is a top brand battery. Sam's price is really good.

There’s never a problem with the batteries at Sam’s Club. The recent problem that I’m experiencing is with the purchase of London broil meat. The meat looks terrific in the packaging when you get at home and turn it over hidden underneath is all sort of fat and gristle and parts that you cannot eat it only adds weight to the cost. It’s almost like bait and switch. I’m hoping Sam’s Club can trim off the unusable pieces or flip the meat over when packaging it so we can see what we’re purchasing.

Utilize these batteries in my smoke alarms. However, every one of these in the pack was bad. When I installed in the Smoke alarm, the alarm began beeping. Used a different battery from the pack and beeping continued, I repeated in other alarms with the same result, beeping. I bought a pack of 4 at a local retailer, and ALL 4 were good.

Almost half the batteries in the pack were dead

I bought these for our fire detectors, you know the ones that seem to always die in the middle of the night (beep, beep, beep, beep). I replaced the batteries in 2 of the detectors two weeks ago and they are already dead (insert annoying beep, beep, beep, beep . . . ). Not sure what happened to these batteries before I got them but they are not good!
